Definitions
- the present invention concerns improvements in coated materials, and more especially concerns platinum group metal-coated ceramics.
- Slip-cast and sintered ceramic refractories are used extensively as parts for the handling of aggressive materials such as molten glass.
- Such sintered ceramic refractories are generally manufactured by forming a dense slurry of the refractory oxide, optionally in the presence of inorganic binding agents, casting the slurry in a mould and sintering the resulting cast item.
- Such refractories are considered to be of low density, and generally exhibit up to 15-20% of interconnecting porosity.
- Chemically, such refractories are mixtures of two or more of silica, alumina and zirconia, although other oxide components such as magnesia may be present, plus additives and impurities that may promote sintering etc.
- fusion-cast refractories the chemical constituents are generally fused by electric arc melting using graphite electrodes, and cast into moulds or flowed onto enclosed surfaces.
- the fusion-cast refractories find widespread use as furnace lining blocks and channel blocks and in furnace and reaction vessel linings (sometimes called "glass-lined vessels") and generally exhibit improved resistance to corrosion or erosion compared to low density refractories. The same is also true for the less commonly used pressed, engineering refractories mentioned above.
- fusion-cast refractories and the pressed engineering refractories exhibit high performance in use, under extreme conditions they are still prone to attack and ultimate destruction.
- high performance refractories are subject to attack at or below the line of molten glass.
- the lifetime of such components is determined by temperature, glass-type and the amount of glass processed. Damage to these refractories, because of their use in strategic locations, can lead to the need for partial or even complete shut-down of the furnace and loss of production.
- the present invention is believed to be applicable not just to fusion-cast and engineering ceramics for the glass industry, but to supported or unsupported ceramics and glasses which exhibit the same characteristics of at least a dense, low-porosity surface to which sprayed metals or similarly deposited metal films, show poor adhesion. All such materials are to be considered as metallic-oxide ceramic refractories within the scope of the present invention.
- the present invention provides a refractory metallic-oxide ceramic part suitable for use in the processing of molten glass, said part possessing at least one surface area having a surface drilled to develop an array of slots or closed-end holes, and in which at least a portion of such treated surface carries a platinum group metal or platinum group metal alloy coating pegged thereto by the mechanical interaction between metal pegs formed as part of said coating and positioned within said slots or holes and the ceramic walls and bases of said slots or holes.
- a suitable industrial laser can have substantially the same effect, is operational in a normal air atmosphere, and by using a fibre-optic delivery system attached to a multi- axis positioning system, the laser profiling can be achieved on both planar and non-planar surfaces.
- a pattern of cut blind holes or indentations or slots can be achieved on a macroscopic scale, which is effective to give a keyed surface to which flame-sprayed metal adheres surprisingly well. It is not necessary for any of the blind holes, indentation or slots to have a re-entrant shape. It is not believed that the profile pattern is significant in achieving the remarkable results of the present invention, and it is thought that almost any regular, irregular or even random profile is effective.
- the holes have a depth to diameter ratio of greater than one, preferably from 3 to 6, and slots have a width to diameter ration of greater than one.
- Holes desirably have a diameter at the surface of the ceramic of 200 to 500 microns.
- Slots desirably have a length to depth ratio of less than three; slots preferably have a width of 200 to 500 microns at the surface of the ceramic.
- Slots need not be simple slots but may incorporate one or more changes in direction, and may intersect.
- the spacing of holes or slots in an array may be determined according to the particular ceramic by routine experiment, but this is suitably less than 20 times the hole diameter.
- a preferred linear spacing is approximately 1 mm.
- the invention also provides a method of metal coating a metallic-oxide refractory ceramic part, comprising treating at least one surface area of said part using a high energy beam to remove a portion of surface area, to form a plurality of slots or closed-end holes which form an effective bonding surface, and subsequently depositing a coating of a platinum group metal or alloy thereof, onto the bonding surface to provide mechanical interaction between metal pegs formed as part of said coating and positioned within said slots or holes and the ceramic walls and bases of said slots or holes.
- One surprising aspect of the experimental work has been the discovery that the flame or plasma sprayed metal penetrates deeply into the patterns cut by the energy beam and fills them without developing local through coating porosity.
- the metals useful in the present invention are one or more of the platinum group metals, namely platinum, rhodium, palladium, ruthenium, iridium and osmium, and alloys with each other or with base metals.
- the metal is platinum, an alloy of platinum, eg Pt5%Au, Pt10%Ir, Pt10%Rh, Pt5%Ru, or Pt with up to 1%Zr, or grain stabilised Pt or Pd.
- platinum platinum
- platinum platinum, an alloy of platinum, eg Pt5%Au, Pt10%Ir, Pt10%Rh, Pt5%Ru, or Pt with up to 1%Zr, or grain stabilised Pt or Pd.
- the refractory part may be of any of the conventional fusion-cast refractory or pressure formed engineering refractory compositions, incorporating one or more of SiO 2 , Al 2 O 3 , ZrO 2 and MgO 2 , optionally including amounts of other refractory oxides such Cr 2 O 3 .
- AZS alumina/zirconia/silica
- Such high density engineering refractories are not defined by nomenclature but by suitability for the most arduous glass furnace applications.
- Other similar refractory parts, such as fusion-cast chromias may be platinum-coated using the present invention.
- zirconia In the casting process, zirconia has the highest melting point of the regular components of an AZS refractory, and tends to crystallise preferentially at the surface of the mould. This can result in the surface of the fusion-cast part not being representative of the bulk material, and can be less amenable to treatment. It may be desirable in such cases that the surface of the part is machined to expose bulk AZS material; in manufacturing certain parts this was done conventionally as part of the manufacturing process.
- one or more intermediate metal oxide and/or metal layers may be applied, using conventional methods or methods known per se .
- the platinum group metal may be deposited on the surface of the refractory part in a number of different ways.
- a preferred method is by combustion flame spraying in a method analogous to that described in EP 0 559 330 .
- Other methods include plasma flame spraying, and high velocity oxy-fuel combustion spraying. Further methods may be developed without departing from the scope of the present invention, and, for certain uses, sputtering or CVD may be appropriate.
- the metal coating desirably has a thickness of 50 microns up to 2mm (the thickness is probably limited only by the economics). More desirably, the thickness is 50 to 500 microns, suitably about 200 microns.
- platinum-coated fusion cast refractory and high density engineered refractory ceramic parts according to the invention are corrosion resistant at temperatures of up to 1600-1650° C. This can increase the processing options and materials available to furnace users.
- the platinum group metal film may be connected to a source of electricity in a manner that permits resistance heating of the film. This can permit good temperature control of furnace contents and may reduce viscosity of furnace contents such as molten glass, in appropriate parts of the furnace.
- Patterns 1 to 11 were prepared using the EB gun inside a vacuum chamber on a single block of fusion cast ceramic ER1711. The specific conditions of the processing were recorded and defined, but since these are specific to the particular EB gun and equipment, these conditions are not defined here. In practice the conditions required to define any selected pattern would need to be defined for the specific EB unit.
- Table I Patch Pattern 1 Short lines, basket weave 2 Short lines, basket weave 3 Short lines, basket weave 4 Lines unbroken? 5 Lines unbroken? 6 Short lines, basket weave 7 Faint lines 8 Square grid of holes 9 Square grid of holes 10 Rows of holes 11 Square grid of holes
- the level of ceramic movement from the zones of highest beam energy was considered extreme for some pattern types, specifically the weave and slot patterns.
- the decision was made to grit blast the as treated surfaces.
- the images shown in Figure 1 are of the surfaces after the grit blasting.
- the coatability was excellent with the pattern being less important than having disrupted the surface very significantly to create holes or slots.
- the additional benefit of the strong bond between coating and "pattern" was a carry over to the untreated areas of ceramic between the treated patches, where is appears that the bonding generated by the treatment has reduced interfacial stresses sufficiently to allow these regions also to be satisfactorily bonded.
